Abstract:
    In accordance with an implementation of the present technique, a detector is disclosed. The detector includes a photodetector array and a substrate layer. The photodetector array includes a plurality of photodiodes and a structure of trenches or diffusions grids that electrically isolate each photodiode of the plurality of photodiodes. The plurality of photodiodes and the structure of trenches or deep diffusions grids are disposed on a first surface of the photodetector array and a second surface opposite the first surface is bonded to a substrate layer. The substrate layer is typically made of the same semiconductor material as the photodetector array but heavily doped and conductive to provide cathode contact to the photodetector array in addition to mechanical support.
